Mitsubishi Outlander XL. Manual - part 794

STEP 9. Check the wiring harness between KOS-ECU
connector C-102 (terminal No. 11, 12, 32) and receiver
antenna module connector C-30 (terminal No. 2, 1, 8).

Q:Is the wiring harness between KOS-ECU connector C-102

(terminal No. 11, 12, 32) and receiver antenna module

connector C-30 (terminal No. 2, 1, 8) in good condition?

YES:

Go to Step 10.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. Verify that the high-beam
headlights illuminate normally.

STEP 10. Check the power supply circuit to the reciever
antenna module. Measure the voltage at reciever antenna
module connector C-30.

(1)

Disconnect reciever antenna module connector C-30 and
measure the voltage available at the harness side of the
connector.

ZC501040056

Harness side: C-30

(2)

Measure the voltage between terminal No. 3 and ground.

｠

The voltage should measure 5 volt.

Q:Is the measured voltage 5 volt?

YES:

Go to Step 11.

NO:

Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.)

STEP 11. Using the oscilloscope, check the waveform at
receiver antenna module connector C-30 and ground by
backprobing.

(1)

Do not disconnect the receiver antenna module connector
C-30.

(2)

Connect an oscilloscope to receiver antenna module
connector C-30 terminal No. 3 and ground by backprobing.

Normal waveform

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

｠

Check the waveform.

Q:Is the waveform normal?

YES:

Go to Step 12.

NO:

Replace the receiver antenna module.

STEP 12. Check of the troubles.
Check that the IG turns (keyless operation is recognised).

Q:Dose the IG knob will not turn (keyless operation is not

recognized) in good condition?

KEYLESS OPERATION SYSTEM (KOS)

DIAGNOSIS

YES:

The procedure is complete.

NO:

Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.)

Inspection Procedure 5: The engine will not start with KOS (IG knob operates normally).

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.42B-10."

(2)

Turn the ignition switch to the "ON" position.

(3)

Diagnose the CAN bus line.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the CAN bus line found to be normal?

YES:

Go to Step 2.

NO:

Repair the CAN bus line. (Refer to GROUP 54D,

Diagnosis P.54D-17).

STEP 2. Using scan tool MB991958, read the KOS-ECU
diagnostic trouble code.
Check if DTC is set to the KOS-ECU.

Q:Is the DTC set?

YES:

Troubleshoot the KOS. (Refer to P.42B-18.)

NO:

Go to Step 3.

KEYLESS OPERATION SYSTEM (KOS)

DIAGNOSIS

STEP 3. Using scan tool MB991958, Check the configuration
function.
Use the ETACS-ECU configuration function to check that the
"KOS feature" is set to "Both enable" or "ENG strt enable".

(1)

Turn the ignition switch to the "ON" position.

(2)

Use the ETACS-ECU configuration function to check that the
"KOS feature" is set to "Both enable" or "ENG strt enable".

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is it set to "Both enable" or "ENG strt enable"?

YES:

Go to Step 4.

NO:

Use the ETACS-ECU configuration function to set the

"KOS feature" to "Both enable" or "ENG strt enable".
(Refer to P.42B-170.)

STEP 4. Check that the engine starts.

Q:Does the engine start?

YES:

The procedure is complete.

NO:

Refer to GROUP 13Ab - Troubleshooting P.13Ab-44.

INSPECTION PROCEDURE 6: No Door will be Locked or Unlocked by Operating A Lock
Switch On Any Door, or by touching The Unlock Sensor.
